Bastnasite and Gibbsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Bastnasite and Gibbsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bastnasite and Gibbsite Optical Properties during the identification of gemstone. Specific gravity of Bastnasite is 2.35 whereas that of Gibbsite is 2.35.
